Support for the ARM 64 bit CPU architecture (aarch64) was introduced in autoconf 2.69. gtk+ appears to use an earlier version of autoconf, preventing its being built. This can be fixed in of three ways (In order of preference): 1. Work with upstream to migrate the package to autoconf 2.69. 2. Rerun autoconf or autoreconf in %prep or %build prior to running configure. 3. Apply the patch at http://ausil.fedorapeople.org/aarch64/gtk+/gtk+-aarch64.patch which updates config.guess and config.sub to recognize aarch64.
As with the glib package, this one copies in config.guess and config.sub from /usr/lib/rpm, which I believe to be sufficient for aarch64 support.
